Improvement in self-tilting bucket for wells



and I do hereby declare that the followin UNITED STATES AARON J. COOK, OF NORTH BBANFORD, CONNECTICUT.

IMPROVEMENT IN SELF-TILTING BUCKET FORA WELLS.

Specication forming part of Letters Patent No. 55,062, dated May 29, 1866.

To all whom it ma/y concern Be it known that I, AARON J. COOK, of the town of North Branford, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Apparatus forDrawin g Water or in Self-Tipping Buckets; g is a full, clear, and exact description of the construction, character, and operation ofthe same, reference being had to theaccom pan yin g drawings, which make part of this specication, in which- Figure 1 is a perspective View of the whole apparatus as it will appear while emptying the bucket. Fig. 2 is a perspective view of the same, showing the relative positions of the parts when the bucket is ascending or descending.

My improvement consists in the two cords or chains of equal length, insuring thevright position of the bucket for emptying, and the flanges of the pulleys on the shaft in such a manner that the bucket is sure to entirely discharge the water in the right direction, and at such an elevation that it will always be convenient to hang a pai-l upon the hooks of the spout or set an ordinary tub under the spout, notwithstanding the snow or ice which may ordinarily accumulate, without having the shaft so high as to render the use of the crank inconvenient.

I make the well-curb AA A of wood or any other suitable material, substantially in the form of the four sides of a hollow cube, as shown in Figs. 1 and 2, or of any other convenient shape, with a suitable spout, as B, Figs. 1 and 2, through which the water is to be poured into the pail or other receptacle; and on opposite sides, in proper proximity and relation to the spoutB, I make two notches, as shown at a and b, or any othersuitable bearings for the journals ofthe shaft.

I make the shaft C, Fig. 2, of iron or any other suitable material, with suitable journals, as c, Fig. 2. On this shaft C, I lit two pulleys, barrels, or drums, as D and E, to which I fasten the cords or chains, and on which they wind or unwind in raising or lowering the bucket 5 and on each of these drums I have two lian ges, as f and g and It and t'. Those on the two outer ends, as fand t', are designed solely to prevent the cords or chains e and d from running 0H, and should be made of suitable diameter for and the two, g and h, on the two that purpose 5 inner ends, besides keeping the cords in place, are intended to act upon the ears lf: and lof the bucket both to steady and guide it while being' tippedI directly into the spout B, as shown in Fig. 1, so that the radius of each must be somewhat greater than the semi-diameter of the bucket G, so as to carry the upper end of the bucket so far back as to pass up perfectly free behind the shaft until about one-third of the bucket G is above the shaft, when, as the ears k and Z pass over, the side of the bucket G will strike the shaft C, Fig. 2, and will be tipped to the position shown vin Fig. 1, to empty the water through the spout B into the pail or tub.

I make the bucket G in the usual form, but without bail, and have the ears c and l extend for a short distance horizontally from the bucket, as shown at k and Z in Figs.,1 and 2. I make a. crank, H, and place it on one end of the shaft C in the usual way, with a suitable ratchet-wheel, m, and pawl a, as shown in Fig. l.

Having made `the several parts, as before described, I attach the chords or chains d and c to the pulleys D and E and to the ears 7c and lof the bucket G, throw off the pawl n, and let the bucket down to till it, and then revolve the crank H in the direction indica-ted by the dart until the bucket Gr comes up to the rear ofthe shaft C, as shown in Fig. 2, and as the, ears 7c and l strike the peripheries of the disks g and It they will pass along on those peripheries until the bucket G is tipped to the position shown in Fig. 1, and its contents are poured through the spout B into the pail hanging on the hooksp and q, Fig. 1, or a tub set under that spout, when the bucket may be again l'et down to be again filled, and a break maybe fitted to govern the descent of the bucket, if thought best at any time.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination and arrangement of the shaft C, drums D and E, and the bucket G, suspended on cords or chains of an equal length, the whole being constructed and arranged substantially as herein described and set forth.

A. J. COOK.
